IMPROVEMENT IN MACHINES FOR BENDING- BAG-FRAMES.

The ScheduIe referred to in these Letters Patent and making part of thesame.

To all 'whom it may concern Be itknown that I, GEORGE HAVELL, of Newark,in the county of Essex, and in the State of New Jersey, have inventedcertain new and useful Improvements in Machine 4for Bending Bag-Frames;and do hereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings,and to the letters of reference marked thereon.

b The nature of my invention consists in the construction audarrangement of a machine for bending bag-frames,7 which will behereinafter fully set forth.

In order to enable others skilled in the art to which my inventionappertains, to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the anneved drawings, whichform a part of this specification, andin which- Figure 1v is a planview'of the machine, showing it in its position after the bag-frame' hasbeen bent;

Figure 2 is a front elevation in the same posit ion;

Figure 3 is a front view ofthe former Figure 4 is a plan View oftheformer on its carriage, in posit-ion before thebag-frame is bent; and

Figiue 5 is au end view of the formen A represents the frame or bed ofthe machine,rrest ing on-legs, B B, or other suitable supports.

0n each side of the* bed A is a standard, C, of suitable height, andthese standards are connected by a cross-thai', D.

Along the sides of the frame A, inside of the standards O C, aregrooves, a a, in which the carriage E moves.

Said carriage being moved backward or forward by means of a screw, F,which passes through a female screw on the under side 'of the carriage,has its bearings in the ends of the frame A, and is turned in eitherdirection by a crank, G, or other suitable means.

On top of the carriage E, and across its centre, is placed the bed H,.for the former7 I, the former7 being secured to said bed at itsiontside.

The former I is provided with wings, I I', pivoted, one to each end ofthe main portion ofthe formen The whole formen thus constructed, isprovided with a groove, b, along its entire length, in which groove oneside of the bag-frame is inserted, the wings I l being on a line withthe main body I.

The bed H is of such size that when the wings are turned backward, theyshall rest on or against the same, at right anglesA with the centreportion I.

The ends of the centre port-ion I, and the inner ends of the wingsl 1',are so constructed, that when the said wings are so bent backward, thecorners shall be rounded, so as to form the bag-frame in the propershape.

'lhe sides of the bed H, just above the carriage E, are provided withcogs, which continue around the corner, and a suitable distance inwardon the front side.

Through the cross-bar l) are passed two journals, c c, which areprovided, on the upper side of the crossbar, with levers or handles, JJ, and under said crossbar with arms, d (l. y

These arms are, at their .outer ends, provided each with a flangedroller, e, extending downward from said arms, and turning on a shaft oraxle secured to the arm. v l

The arms d d areof such length, that when turned parallel with thecentre portion I', of the fol-mer, the rollers c e shall be immediatelyat the rounded ends of said centre portion, and the flanges on therollers e e be one above and one below the wings I,

or rather, the wings will fit in between said flanges.

Under the lower flanges the rollers e c are cogged, to correspond withthe cogs on the bed H.4

The metal from which the bag-frame is to be made, is first bent in theshape shown in fig. 5, (said metal is marked i one side is then insertedin the groove D, in the foi-men7 the wings I I being extended, as Vshown in iig. 4.

The handles or levers J J are now placed together, bringing the rollerse e in the proper position, when the carriage E is started.

As soon as said carriage has moved far enough for the wings I' I' tostrike the rollers e e, they are turned backward, bending the metal twith it to the proper shape, the cogs above mentioned causing therollers to rotate, and shaping the frame properly.

The former I, with its wings, may be made of two plates fastenedtogether, leaving a space along the front edge, for the insertion of themetal.

Having thus fully described my invention,

What I claim as new, and desire to secure by Letters Patent, is

l. A machine for bending bag-frames, so constructed that the netalforming the sides of the frame is held or passed between two plates orin a groove, while it is heilig bent, substantially as herein set forth.

' 2. rIlhe former,7 constructed as described, of a centre,`I, havingwings I 1 pivoted or hinged to its out-er ends, when the said foi-mer7is grooved, or made of two plates, leaving a space along the front edgefor the insertion of the metal forming the frame, substantially asherein set forth.

3. The combination of the carriage E, bed H, and former II., with amechanism for causing the blank to bend, all constructed and arranged tooperate substantiall y as herein set forth.

4. The cogged and flanged rollers ce, in combination with the cogged bedH, substantially as and for the purposes herein set forth.

In testimony, that I claim the foregoing, I have hereunto set myhand,this 22d day of February, 1869.

' GEORGE HAVELL.
